If you are serious about competition shooting, the Sig Sauer P320 has probably been on your radar for quite some time and you are probably familiar with the Legion series of upgraded pistols. Now you can enjoy quality and reliability of the P320 with the new X5 Legion model. The Sig P320 XFive Legion features the same frame shape with a high beavertail and undercut trigger guard for better recoil management but is made from a brand new material. The XFive Legion grip frame is made from a tungsten infused polymer that gives you the weight of steel with the flex of polymer to further reduce felt recoil and muzzle flip. Combined with the new grip module is a skeletonized flat faced trigger that reduces the pull weight by about 30% for fast and accurate follow up shots. Another upgrade included with this model is the steel guide rod with a 14 pound 1911 style recoil spring but also includes a 12 pound spring so you can swap them out depending on ammo preference.

  • 5” 9mm bull barrel
  • Tungsten infused polymer grip module
  • Signature Legion Grey finish
  • Skeletonized XSeries flat face trigger
  • Dawson Precision adjustable fiber optic sights
  • Slide cut for Sig mini red dot sights
  • Steel guide rod with 14lb and 12lb recoil springs
  • Removable grip weight and flared magwell
  • Includes 3 17-round magazine with Henning aluminum base plates
The Sig Sauer P320 X5 Legion comes with the signature grey finish on the lightweight slide and frame. On the other side of those weight reducing window cuts is the 5” precision bull barrel that—when combined with the Dawson Precision fiber optic adjustable sights—allow you to be as accurate as possible. The 3 17 round 9mm magazines included with this handgun also feature Henning Group aluminum base pads to help them drop freely faster without fear of them breaking. The removable flared magazine well makes reloads a breeze and the grip module comes with a removable weight.The slide is cut for use with the Sig Sauer Romeo red dot sight right out of the box, so you don’t have to spend money and time sending it off to a gunsmith. The Sig Sauer P320 XFive Legion Handgun offers a competition ready experience without the headache of making the upgrades yourself. Everything comes from the factory with precision fit and finish that blows other competition guns out of the water.Sig Sauer is a world-renowned firearms manufacturer with a rich history of innovation and design leadership.

Need a lot of trigger work


I used to own the Maxwell version of this pistol and traded it in for a CZ and Walther PDP. You would think that a pistol that was supposed to be made for competition would have a great trigger, but I was seriously disappointed the CZ, Canik, and Walther triggers are far better options than the Sig Sauer P320.
